How do I import a minecraft rig into my scene?
You can also append Groups. So if you first Group all your parts CtrlG and name them you will then be able to navigate to this Group using the file browser when you Append.

Immediately after you create a Group you will be given a chance to name it in the Operator Panel on the left side of your 3D Viewport. If you don't see your Tool Shelf which contains the Operator Panel, you probably just need to press T while your cursor is inside the 3D Viewport to make it appear.



If you later need to browse your groups, you can do it in the Outliner. Double-clicking on the Group's name will allow you to rename it.



To see if an object is in a Group, or to add it to or remove it from a Group, you can go to the Object Context to manage this. You can rename groups from here as well.
